Last Updated : 11/25/20193 min read

For most prescription drug coverage you will need Medicare Part D offered by a private insurance company. You can get Medicare Part D through a stand-alone Prescription Drug Plan or a Medicare Advantage plan with prescription drug coverage. You can get a stand-alone plan to go along with Original Medicare. Medicare Advantage is another way to get all your Medicare benefits in one plan. (Only hospice care is still covered through Medicare Part A.)

Prescription medications

All Medicare Part D plans don’t necessarily cover the same prescription drugs. Each Medicare prescription drug plan has a list of covered drugs called a formulary. The formulary may change at any time but the plan will notify you when necessary. Most Medicare prescription drug plans place medications on different tiers, with each tier corresponding to a different cost. Prescription drugs on lower tiers generally cost less than those on higher tiers. You can search for a plan that covers the prescription drugs you are currently taking.

Over-the-counter medications

Generally Medicare Part D does not cover over-the-counter medications such as Advil, Benadryl, or Pepto-Bismol. Some Medicare Advantage plans, sometimes referred to as Medicare Part C may cover over-the-counter items as supplemental benefits. .  Although, Medicare drugs plans are not required to cover over-the-counter drugs there are some exceptions, some plans may cover them as an added benefit.
